This trail is always going up and down (can be hard on the knees, especially if you have backpacks) and can be dangerous when there is fog, rain and big winds. We had for two days, starting from Pico Areerio to Boca do Encumeada only fog and little rain... it was sad. But if you can have a good clear sky this, is an epic hike to do and you can camp along the way! We were the only one hiking this trail in early May, because it can be temporarily closed, so beware!
